Moisture deflection apparatus for aerial vehicle cameras

This disclosure describes deflecting moisture out of the field of view of an imaging device during operation of an aerial vehicle, such as a UAV. The imaging device and/or a deflector positioned in the field of view of the imaging device is positioned within a path of a propulsion motor air disturbance. The deflector protects the lens from environmental conditions, such as moisture and rain and is positioned such that the force of the propulsion motor air disturbance moves any moisture, rain, or other debris contacting the surface of the deflector across the deflector surface and out of the field of view of the imaging device. As a result, distortion of image data generated by the imaging device as a result of water or moisture on the lens or in the field of view of the lens of the imaging device is reduced, if not eliminated.
